HMC129

GaAs MMIC DOUBLE-BALANCED

MIXER, 4 - 8 GHz

v04.1007

General Description

Features

Functional Diagram

Typical Applications

The HMC129 is ideal for:

• Microwave & VSAT Radios

• Test Equipment

• Space Telecom

The HMC129 chip is a miniature double-balanced

mixer which can be used as an upconverter or down-

converter in the 4 to 8 GHz band. The chip can be

integrated directly into hybrid MICs without DC bias

or external baluns to provide an extremely compact

mixer. It is ideally suited for applications where small

size, no DC bias, and consistent IC performance are

required. This mixer can operate over a wide LO drive

input of +9 to +15 dBm. It performs equally well as a

Bi-Phase modulator or demodulator. See the HMC136

data sheet.
